HENRY IB. LANDAU, OF SANDUSKY, OHIO, ASSIGNOR TO GENERAL CHEMICAL COMPANY,

OF NEW YORK, -N. Y., A CORPORATION OF NEW YORK v BAG MACHINE Application filed. .Tune 7,

In existing commercial life many commodities are advantageously stored and transported in bags of jute or similar material; because of the character of the merchandise it is r desirable in many cases to provide such bags provision of means whereby stenciling of the bags or the application of other marks thereto is facilitated. Other objects will appear from the description hereinafter and the features of novelty will be pointed out in the appended'claims. r p

In the accompanying drawing, which illustrates an example of the invention without defining. its limits, Fig. 1 is a perspective view of the machine and Fig. 2 is aside elevation thereof. I

As shown in the drawing the apparatus consists of a suitable support 10, which may be in the form of a bench or table, and a carrier 11; the latter may be in the nature of a rectangular frame of. any. suitable material such as metal rods, bars or pipes and is pivotally connected at 12 with suitable pivot blocks or the like 13 fixed upon the horizontal bed or supporting surface 14 of the support 10 near one endthereof. At its free end a the carrier 11 is provided with light tension springs 15 located upon opposite sides thereof and constructed and arranged to exert tension in outward directions for thepurpose to be more fully set forthhereinafter. A. counter-weight 16 is mounted upon the carrier 11 in a manner to counterbalance the same and is located incontiguous relation to a stop 17 projecting upwardly from the bed 14; the stop 17 is of such dimensions and arrangement as to permit'the free end a of the car'- rier 11 to be swung to a predetermined extent in a direction away from the bed 14 within 1824. SerialNo. 718,458.

the lateral limits defined by the sides of the bed,or in other words to allow an up and down motion'sufi'icient to permit a bag to be readily combined with the carrier as will appear more fully hereinafter. In the normal condition of the parts, the free end a of the carrier ll rests upon a stop 18 secured upon the bed 14 as shownin Fig. 1. A second carrier l9iwhich may be a duplicate of the carrier 11 and likewise comprise a rectangular frame of suitable metal, is pivotally connected at 20 with pivot blocks 21 mounted upon the bed 14; the carrier 19 does not require tension' springs such as the springs 15. The second carrier 19 is also provided with a counter-weight 22 which-is so located and arranged as to permit the carrier 19-to be swung on its pivots 20 through an arc of one hundred andfeighty degrees. The arrangement of mounting the carriers is such that the carrier 19 may be swung to a position in which it projects toward the carrier 11 and has its free end 6 resting upon the stop 18 in close proximity to the free end a of said carrier 11 as shown inFig. 1. The path and direction of movement ofthese carriers 11 and 19 in relation tothe bed 14 is so governed by the mounting constructions that the are described by any point on the moving carriers Will liewithin the lateral limits defined by so the sides of the bed and in a plane perpendicular tothe plane of the surface of the bed. 'It will be understood that the carriers 11 and 19 arepivoted at the sameheight so as'to be located at a common level when projecting to- .ward each other as in Fig. 1 and that. said 7 carriers are somewhat longer than the length of the bagsto be accommodated and somewhat less in width than the width of said bags.

In addition to the parts so far described the apparatus includes a stop 23 located upon the bed 14 of the support in a position to provide a rest for the end I) of the second carrier19 when the latter is swung to the position shown by dotted lines in Fig. 2. At a point upon the bed 14 between the stop 23 and the pivot blocks 21 a stencil block 24may be provided to permit the bag to be stencilled upon one side before it is removed from the apparatus. Suitable means may be included for 100 also stencilling or otherwise marking the other side of the bag if this should be desired. The stencilling may be accomplished by means of any suitable stencilling device and if desired may include means whereby ink is sprayed by compressed air through a stencil from below.

In practice a supply of jute or other bags is placed upon the bed or in any other convenient location with their open ends projecting toward the carrier 11 and a supply of empty bag liners is likewise placed in position within convenient reach of that end of the support 10 at which the stop 23. is located.

The apparatus is preferably manned by two operator's one of whom stands at the support 10 near the stencil block 24 andthe other of whom stands at the opposite side of the sup port at a point about in registry with the stop 18'. The latter operator raises the carrier 11 and draws a jute bag over the same, the closed end ofsaid bag being 'interiorly clamped by springs 15', andthen restores the carrier, with Y the jute bag in place thereon, to the position shown in Fig. 1. While these operations are being performed by the one operator, the other places a bag liner upon the second carrier 19, which at this stageoccupies the position indicated by dottedlines in Fig. 2, and then swings the carrier 19, with the liner 7 thereon to the position shown by solid lines in Fig. 1. With the parts in this adjustment the closed ends of the jute bag upon the carrier 11 and the bag liner upon the carrier are in close proximity to and project toward each other, The first operator thereupon grasps the jutebag upon opposite sides at its open endand pulls the bag upon itself or in other words turns it inside out upon the carrier 11 and finallydraws said bag over the liner'upon the carrier 19. This operation is easily caIfried outby reason of the fact that the carriers 1 position the bag and liner at the same level and inexact alignment with each other as shown in Fig. 1. When the jute bag has been fully pulled over the-liner and thereby combined the two, the carrier 19 is swung back to the position indicated by dotted lines in Fig. 2 in which the outer end rests upon the stop 23 and thestencil block 24; is beneath and .in'engagement with the bag at an intermediate point. If desired, a suitable stencil may accordingly be applied, for instance, as

hereinbefore set 'forth, after which the second' operator, by gripping the bag atits bottom, pulls thelinedbag from the carrier 19 and places it on a truck orstock-pile or otherwise disposes of it.

A new bag ismeanwhile being placed upon the carrier 11 and a new liner. drawn upon.

the carrier 19 and the same cycle of operationslis repeated in se'quence; During the transferof the bagfrom the, carrier 11 to the carrier 19'the closed end of said bag is held by the springs 15 so thatturning said bag inside out and placing over the liner is accomplished without difficulty. If desired, provision may be made for applying astencil or other mark to'the bag directly after it has been drawn over on the liner upon the carrier 19 so that said bag may be stencilled ormarked in'two places.

The invention provides a simple and efficient apparatus for quickly and easily lining ranged and constructed to carry a' bag and a liner respectively, each carrier being pivoted to move independently in a vertical plane into cooperative relation with the other.
